use tonic::service::Interceptor;
use tonic::transport::Channel;

pub struct GrpcClient<I>
where
   I: Interceptor,
{
    grpc_channel: Channel,
    auth_interceptor: I,
}

impl<I> GrpcClient<I>
where
    I: Interceptor + Clone,
{
    /// Get auth params
    #[grpc_method(AuthQueryClient::params)]
    async fn get_auth_params(&mut self) -> Result<AuthParams, Error>;
}
